Traffic fumes in cities linked to increased cancer, heart disease risks

I occasionally eat bacon. Not often, but occasionally. A girl I knew learned of this and she decided to straight-up lecture me about how awful bacon is. “It is shown to cause cancer!” First, she had no idea what a nitrate was, when I asked (lol), but secondly, she lives in downtown Phoenix. Right downtown. She did not seem to get it. “BUT BACON!”

She also smokes (I do not). Ugh. Hippies.
